>>6160953Have to wait like a minute, then you only have like 5 minutes to do it. IDK, if you are on mobile, might be harder. I highly suggest getting Greasemonkey or Tampermonkey on your browser, installing 4chanX. Makes it a bit easier to do, IMHO; that extension also lets you see deleted posts as well as a bunch of other nice things. Used 4chanX for so long, I am spoiled.
Click the little radio button on your post. Go to bottom right of thread. Hit the delete button.
Boom.
Yes I know, lurk moar, spoon-feeding, ect but this is a small board. Might as well be hospitable.
